5 Claims. (Cl. 215-38) This application is a continuation of applicatlOIi Ser. No. 148,468, filed June 16, 1937.

. This invention relates to packages of, and

5 methods of packaging, tablets. The term tablets," as herein employed, means small concreted objects of any shape or kind.

Tablets are generally friable or frangible, and precautions are ordinarily taken in packaging between the uppermost layer of tablets and the shoulder, wall, and/or closure of the container.

For example, pharmaceutical tablets are ordinarily packaged in small bottles and immobilized m by means or cotton wedding. To obtain access to the tablets, the container closure is removed, and

' the resilient packing manually withdrawn. However, unless the packing happens to extend to the edge of the container mouth, which is unusual.

as .the removal of the packing becomes a troublesome operation, often necessitating resort to a suitable implement, especially if the container mouth is narrow.

It is an object of this invention to provide a so package oi, and a method of packaging, tablets a the packing.

such that the packing can easily be removed. In the practice of this invention, the packing is aiilxed to the closure, sothat removal of the lustrated in the drawing, wherein: l

Fig. 5is a vertical sectional view of a package 5;; having-a cork closure.

Figs. 6 to 9, inclusive, are further modifications of the invention embodying structural connecf tions between the closure and the packing.

Figs. 1 and 2 show a bottle ll partially filled as with tablets l2 and containing thereabove a suitable flbrous packing H, which may be cotton wedding. shredded paper, or other material of similar characteristics. The lower surface of the packing is in contact with the uppermost layer of tablets, and upper surfaces of the packing are in contact with the walls and shoulder of the bottle; 'and the packing also extends up to the lower face of the unlined or lined screw-cap or preciable portion of its uppermost extremity exm o p t their being m e 183$ reduced 01 the liner ii in the screw-cap l8, and is affixed w to fragments and powder by the impacts and t eto by a spot of glue ll. movements involved in transporting and hsn- Thi package may be assembled by th followlins the package.- Such precautions u l ing procedure: The container is partially filled take the form of immobilizing the tablets within with tablets andthe packing material is t s the package by insertion. of a resilient packing duced in such amount d position that an ap- 15 tends a little above the plane to be occupied by the lower face of the closure. A spot of adhesive is placed in the center of the lower face of the closure, and the closure is then pushed or screwed into position.

Fig. 3 shows the packing material in the form of a strip of cotton wadding 2|, which may be of circular or rectangular cross section. one

end 24' of the wadding is glued at ii to the under {ace of the unlined or lined screw-cap or of the cork liner I! in the screw cap it.

Fig. 4 shows a strip of cotton wadding 24 attached at one end to a screw cap IS. The attachment is eilected by passing one end of the strip 24 through a slit is in the cap liner it, before introducingthe strip into the vial 8|.

liner, the free end or ends of the metal bein retroserrate. The cap liner is'eitlier' tightly or loosely snapped into a bead formed-in the cap. When the liner or the liner-and-cap combination is applied to the container, the barbs pass into and engage the packing.

Figs. 8 and 9 show a wire shaped into a helix or corkscrew, 38 and 39, and fastened to a cap liner id, as in Fig. 8. Afllxationof the packing to the closure may be accomplished by direct attachment before the packing is inserted into the container, or by twisting or turning the closure during application thereof to the container after insertion of the packing.

The devices described herein facilitate removal of the packing, which is removed simultaneously with the closure or with the lining of the closure, or is raised in the container by the act of removing the closure, sufliciently to enable it to be withdrawn manually.

It is to be understood that the foregoing examples are merely illustrative and not limitative of the invention, which may be variously otherwise embodied within the scope of the appen ed claims.

We claim:

1. In packages utilizing bottles andlike containers and of the character employed in the pharmaceutical trade for distributing tablets, pills, capsules and the like, said package comprising cotton or other integral wadding inserted in the top of the container so as to completely fill the space immediately above the said tablets or other contents and compacted in said space to an extent immobilizing said contents in the bottle to thereby prevent damage to and to exclude moisture from said contents, the combination with said container and said wadding, of a closure for said container, and means for attaching said wadding to the closure, whereby when said closure is released and lifted away from the container the attached wadding is withdrawn from the latter. v

2.
